Section III - Creating an Executable
Although this package was created as a library, we can make it dual binary and library by doing the following:
Modifiy the Cargo.toml file to point to a binary during build time
[[bin]]
name = "hello_world"
path = "src/bin/hello-world.rs"
Create a new bin folder in the src directory
Create a new file hello-world.rs in the bin directory with the following code
pub fn main() {
println!("Hello World");
}
Build and run the package
[user@localhost rust-daas]$ cargo run
Compiling rust-daas v0.1.0 (C:\workspace\rust-daas)
Finished dev [unoptimized + debuginfo] target(s) in 0.67s
Running `target\debug\hello_world.exe`
Hello World
There should now be an executable named hello_world in the /target/debug directory which you can execute directly.
[user@localhost rust-daas]$ cd .\target\debug\
[user@localhost debug]$ ./hello_world
Hello World
